KNEE SIGNAL.

Application filed Jul 13,1920. Serial No. 395,926. h

To all whom'z' t may concern:

Be it known that I, PHILIP H. MARETT,

a citizen of the United States, residing at Philadephia,in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Knee Signals, of which the following is a specification. I

The herein described device relates to attachments forautomobiles and. more particularly to devices adapted to be removabl'y applied and attached to either the steering rod or column of automobiles or. to other parts of the same for the purpose of sounding a horn or actuating some other signal without removing the hands from the steering wheel. a 5

One of the objects of this invention is to provide a simple and practical attachment which can be readily, easily and quickly attached to the steering rod or column or elsewhere on the car, if necessary, without alteration thereof, for the purpose of sounding a horn or other signal, in a quicker and more convenient manner for the driver. A further object is to provide an attachment as herein described which will be inexpensive to manufacture, reliable in use, convenient in operation and of such nature as to enable anyone to attach and use the same.

A further object is to provide a device capable of adjustment in order that it may be conveniently positioned with respect to the drivers knee and operated thereby.

lVhile the foregoing explains the general purpose and objects of the device, other objects and advantages will appear in the specifications that follow, in which the novel features, construction and arrangement of the various parts will be brought out, described and claimed. I

In the accompanying drawings, forming a part of this specification, and in which corresponding parts are denoted by like designating numerals, is illustrated the preferred form of the embodiments of the invention capable of carrying the same into practical operation, it being understood that the invention is not necessarily limited thereto, as various changes in shape, proportions, and general assemblage of the several parts may be resorted to without departing from pressure arm. I r

Figure 9 is a view in perspective showing arm for operating horn blown by exhaust or otherwise.

Coming to the precise details :-the arm 1 which is partially curved at a predeter-v mined point and hollow at one end thereof 10, with the under portion of the hollow end cut out and shaped adapted to and fits over an operating shaft 9 which is also curved, the outer end of the shaft isadapted to enter. the hollow portion ofthe arm, with the cut away section 27 resting in position in the hollow portion and held therein by the pressure of the spring member 11 which is removably secured in the hollow portion of the arm and presses against the shaped portion 12 of the shaft. What might be termed the operating end of the shaft 9 has secured thereon a substantially larger member 3 with the under side cutaway to form the part 13 which is arranged and adapted to press against the spring contact 16, and. either presses against a push button by the medium of the free end of the contact 14, or by electric contact as shown by the members 17 and 18. It is shown that the member 3 is to be enclosed in a casing 2 for the purpose of attaching the device to certain positions, the shaft 9 and the operating member 3 being adjustably secured therein by the threaded portion of the shaft 9 as shown at 24 by simply turning the nut 25 or any securing means of like nature. In order that the casing 2 can be placed in any desired position, the shaped hollow member 4- is provided, which has a portion at its lower: extremity. cut away 8 to adjust itself to a steering rod of any shape, or a post or column, also to the shaped member 21, more particularlyshown in Figure 3, which is attached to any portion of the car as desired by the. simple means of screws at the parts numbered 23. The adjustment is obtained by means of the aliabl metal band 5 adjustably and removably attached to the shaped member by means of the threaded member 6 inserted through the opening in the wing like portion 6", ameniber, T, heavier than the band receiving the threaded portion of the member 6 and permits' of the adjustment of the band to a larger or smaller circumference as desired by the openings 5; When desired to use the device for other than push button or electrical control, the device is attached to any portion of the car'to suit the COnVBnience or" the driver by using the romovably attached member as illustrated in Figure 3. attaching the operating portions thereto, and adjusting the arm to the required position, and using a pull of any desired and well known material, such as wire, as shown by the numeral 26, attached in, a'shaped member removably and adjustably maintained in the said hollow portion and coming into contact with the aforementioned spring, said shaped member curved and having one end threaded, relatively larger member betw ,en the curved portion and the threaded portion with the under side out out adapted to come into contact with a push button or like means, the said relatively larger member removably maintained with a shaped member, the shaped member removably attached to a shaped member of a relatively different outline, and a supple mental attachment to a shaped member adjustably secured.

In testimony whereotI afiix my signature in the presence of two witnesses.
